At the risk of hijacking another thread, I started this one:
How many of you owning the 7.3 PSD check and add the anti-cavitation additive (FW16 I think)?
Do you do it yourself with your own test strips or have a Ford dealer do it?
Thanks.

I hope you added coolant that already had the DCA in it or you added it along with the coolant.
The failure mode is a pin hole in the cylinder wall that separates the combustion process from the coolant. Cavitational Pitting.

When I had the 7.3's, I definately tested myself and added the FW16 (originally FW15) when needed. The only reason I knew to add it on the 1996 7.3 was because I read it on an internet forum post. Some pointy headed genus at Ford forgot to put that nugget of info in the owners manual until 1997 or so.

I bought a packet of strips and checked a couple of times and it always measured good. I finally just dumped in a bottle of additive a couple of years ago and then last year flushed the whole system and put fresh antifreeze in, so I should probably start testing again. Before I bought a packet of strips I stopped in at Ford and asked in the service department and they handed me a few strips. The strips do have expiration dates but I don't know what the failure mode is. The ones Ford gave me were from the package the garage was using and were out of date.

What's IDI?
Are you saying that you use G-05 coolant and change it every 30K and that makes the additive unecessary? The additive is in the coolant that's changed and "refreshed" with new fluid every 30K?

I add the FW additive per the manual every 15000, I think it is-half bottle. Ive never checked with the strips though.

I did until Ford approved the G-05 coolant for the post 99 PSD and changed over to that at 30K mile and have now done two G-05 changes and have 76K miles on my 2001 Van.
The non IDI 7.3 blocks are virtually immune to cavitation so I don't worry too much about it. A Navistar engine engineer at the old Ford-Diesel first Ralley in Ky said that you could run straight water in a 7.3 and the block should last 300K miles before issues might occur.

I did the Gooch Coolant flush and replaced with ELC where no additives or test strips are needed, clicky
I also added the coolant filter from Dieselsite. clicky along with their billet housing. clicky
Although not related to coolant, I also added their external transmission filter kit. clicky
